Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 870+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.
How to install Coinranking MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
Verify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
Codex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on dashboard.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
What is the Coinranking MCP server, and what's possible with it?
The Coinranking MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Coinranking account. It provides structured and secure access to real-time and historical cryptocurrency market data, so your agent can perform actions like tracking prices, analyzing trends, fetching coin stats, and surfacing trending cryptocurrencies on your behalf.
- Real-time coin price tracking: Instantly access up-to-date prices for thousands of cryptocurrencies, letting your agent monitor the market or retrieve coin values on demand.
- Historical performance analysis: Retrieve and analyze historical price data for any coin, so your agent can chart trends and compare past performances.
- Global market overview: Get comprehensive statistics about the entire crypto market, including total market cap, volume, and dominance, all via your agent.
- Discover trending assets: Surface the most popular and trending coins based on user engagement, helping your agent highlight coins gaining traction right now.
- Reference currencies and tags management: Let your agent fetch supported fiat and crypto reference currencies, and retrieve all canonical tags for advanced filtering and categorization.

FAQ
What are the differences in Tool Router MCP and Coinranking MCP?
With a standalone Coinranking MCP server, the agents and LLMs can only access a fixed set of Coinranking tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Coinranking and many other apps based on the task at hand, all through a single MCP endpoint.
Can I use Tool Router MCP with Codex?
Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Coinranking tools.
Can I manage the permissions and scopes for Coinranking while using Tool Router?
Yes, absolutely. You can configure which Coinranking scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.
How safe is my data with Composio Tool Router?
All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Coinranking data and credentials are handled as safely as possible.
